摘　　要：双速风机以往多选配YD型电机,而现在多选用针对风机类负荷更匹配的YDT型电机。这两种电机的定子绕组接线型式是有区别的。目前通用的双速风机控制原理图,大多数是针对YD型电机的△/YY变换。本文就此展开讨论,针对YDT型电机的Y/Y、3Y+Y/3Y、Y/YY变换,给出了主回路接线及电气元件的选取原则。In the past double speed fan mainly uses YD-type motors, but now YDT-type motors are more often used, for such kind of motors can better meet the load requirements of fan. Connection type of these two kinds of motor stator windings are different from each other. At present the principle diagrams of control are used for common double speed fan, most of which are for △/ YY transformation of type YD motors. In this paper discussion about this is made and the selection principle of main circuit connection and electrical components are shown for Y / Y, 3Y ＋ Y / 3Y, Y / YY transformation of type YDT motor.
